$2.00Clear UBOX 厌氧好氧一体化模板
Clear UBOX 厌氧好氧一体化模板 ClearUBOX is the combination of an UASB reactor and ClearBioRoto. It is a biological treatment module, both anaerobic and aerobic. The anaerobic part is at the bottom of the reactor and is equipped with a three-phase separator, which can efficiently retain anaerobic sludge and collect produced methane. Wastewater is well distributed from the bottom of the reactor and enters the anaerobic unit of UBOX reactor. Anaerobic reaction mainly converts biodegradable COD into biogas and the gas-liquid separator collects biogas for further treatment. After anaerobic treatment, wastewater flows up into the aerobic part for following process. The aerobic part is equipped with ClearBioRoto, where the remaining COD is degraded. Water is discharged after passing through the efficient sludge-water separator. The sludge remaining in the aerobic part returns back to anaerobic part for further treatment. This product is especially suitable for domestic sewage treatment. -
$2.00ClearBioRoto
ClearBioRoto A traditional rotating biological contactor, because of its irrational packing structure and insufficient self-purification, results in problems such as disorderly accumulation of sludge. These problems can damage the dynamic balance, gradually increase the rotation torque, and finally damage the transmission device. Therefore, lack of durability becomes a serious defect of rotating biological contactor. To solve the problem, the packing structure must be optimized. ClearBioRoto uses our company’s newly developed 3-D tubular packing unit which is 3-D permeable with a tubular structure. As a result, biological sludge is not likely to accumulate. The specific surface area is as large as 100~200m2/m3. Technical features are as folows: ◆The self-purification of ClearBioRoto can prevent sludge from accumulating. ◆Useless aerobic biofilm can be timely washed out to maintain the durability of the system. ◆Fillers of high specific surface area are used to raise volumetric loading rate (VLR). ◆Plastic material is used to reduce the overall weight of the rotating biological contactor, decrease the rotation torque, and reduce energy consumption. ◆Mechanical structure is specially designed for multi-stage startup to reduce the initial rotation torque. ◆The amount of dissolved oxygen can be adjusted by changing spinning speed in order to realize nitrification and denitrification reaction. -

ClearMBR
ClearMBR ClearMBR separates sludge and water in a manner different from ClearFAR. ClearFAR mixes anaerobic sludge and wastewater by gas stripping. However, it needs efforts to separate sludge and water by three-phase separator or lamellar separator. The process of MBR is mature and stable. It can intercept the sludge completely. When combined with ClearFAR, it can avoid sludge loss, guarantee the concentration of sludge and raise the volume load. The mixture of sludge and water enters the anaerobic tank. After filtration, clean water flows into following the processing unit and concentrated sludge returns to FAR reactor. A MBR unit provides a sealed anaerobic environment. It is connected to FAR reactor to avoid negative pressure caused by suction. The methane it produces enters the gas collection system through FAR. -
$2.00Clear BioScrubber 生物洗涤塔
Clear BioScrubber 生物洗涤塔 A Bio-Scrubber can, when combined with an aeration tank, absorb and biodegrade organic pollutants in exhaust gas in a cost effective manner. It also makes use of the abundant resources of the sludge produced in a sewage treatment plant. The equipment is easy and secure to operate and is especially suitable for removing complex odorous compounds. Exhaust gas containing odorous organic pollutants enters the BioScrubber from the bottom and passes through first stage filtration and spray. Then, the gas goes through gas contributor formed in water-sealed floor and flows upward to second stage filtration and spray. After that, most organic pollutants are either washed into water or absorbed by activated sludge. At this time, the scrubber shuts all its outlets and all the gas is brought from bottom to the upper emission section for discharge, where a defogger is placed to prevent remaining odorous pollutants from re-entering the atmosphere along with fog. The BioScrubber uses active aerobic activated sludge as scrubbing solution, which is able to absorb organic pollutants effectively. The spout can prevent blockage and spray liquid effectively and evenly. After being sprayed out, the activated sludge contacts with air, dissolves a large amount of oxygen while at the same time biodegrades the absorbed organic pollutants (especially acid pollutants). Organic pollutants that are not completely biodegraded will flow back to aeration tank along with activated sludge for further biodegradation. -
$2.00ClearSand连续砂滤
ClearSand连续砂滤 ClearSand intercepts suspended pollutants in wastewater by a deep sand filter bed. The filter bed itself needs to be purified after absorbing pollutants. With the traditional equipment, the processes of filtration and back-washing are divided by time whereas ClearSand, with its centre sand lift column and sand-washer, divides the processes by space and therefore achieves a continuous process of water inlet, filtration, washing and regeneration. Water flow track: Water in need of treatment enters the sand filtration system and will then be evenly distributed throughout the cross-section of the sand filter bed by water distributor. After that, water flows up and the sand blanket intercepts the pollutants. Then, the filtrate flows out through the outlet on the top of the equipment. Sand track: Sand, the filtration material, keeps flowing downward under gravity while water flows upward. The sand, together with the attached suspended matters, passes through centre sand lift column at the bottom of the equipment and is raised by air lifting to the sand-washer on the top. In centre sand lift column, the disturbance of gas and water will detach pollutants from sand. Sand returns back to the filter through the maze in sand-washer, where small amounts of countercurrent wash the sand again. Finally, clean sand returns to the top of the sand blanket and starts the next process cycle. At the same time, filtrate containing large amount of suspended matters is discharged from the outlet. Air track：The circulation of sand is realized by air lifting that compresses the air and the air is discharged from the top of the column. The speed of sand circulation and the intensity of washing can be changed by adjusting the supply of compressed air. -
$2.00ClearLamellar高效斜板沉淀
ClearLamellar高效斜板沉淀 Lamellar separator can achieve a good performance in limited space. A set of large lamellar lined with wide intervals is an effective solution of sludge blockage. The separation of the structure of the box ensures that turbid water pumped in does not contaminate clean water in the outlet; the supporting of reciprocating sludge scrubber ensures that the settled sludge can be concentrated and be discharged promptly. The vertical-flow plate flocculation reactor in the front can achieve various changes in G-value (mixing strength) without stirring. Wastewater that is well mixed with flocculants enters the inlet canal of the flocculation reactor. After that, it flows downward vertically through two compartments and then flows upward. Flowing downward and upward like this, it produces four different G values and forms large particles of alum floc. After entering, the wastewater containing suspended solids flows into the inlet compartments and then goes through the slots on both sides into the plate pack. The plate pack consits of a series of flat plates, which are positioned at an angle. The total settling area and the distance between plates are determined by the settling characteristics of sludge. Sludge is settled on the plate while water flows up; treated water flows out through the outlet valve that is specially designed to enhance settling efficiencies. Water flows up while sludge flows downwards along the inclined plates. Wastewater enters from the side of the plates pack to keep sludge moving and prevent it from accumulating between the plates. Settled sludge is either collected for further concentration in the sludge hopper or removed and discharged by the scrubber, which is easy to operate. -
$2.00ClearRoto旋转滤网
ClearRoto旋转滤网 In the application of solid-liquid separation technology, the rotary separator is the most widely used. Clear Industry’s ClearRoto has various functions: removing suspended matters of tens of ppm to thoroughly purify wastewater, concentrating sludge containing more than ten percent of solids, and screening food waste. Wastewater enters the rotary separator from one end. Rotary drum separator with different separation accuracies separates solids and liquid. With static spiral inside, the rotary drum separator progresses while reversing the solids. Finally, treated water is discharged from the other end of the separator. Water spray is often needed to prevent solid from adhering to or twining round the separator. -
$2.00Clear IC 内循环厌氧反应器
Clear IC 内循环厌氧反应器 IC (Internal Circulation) anaerobic reactor can, through its internal circulation, use the produced gas to agitate the sludge blanket. Therefore, the reactor can prolong sludge retention time to hundreds of days while at the same time shorten hydraulic retention time to a few hours. IC anaerobic reactors must be used with caution when dealing with wastewater that cannot form granular sludge because of calcification and high salinity. Water is pumped into the bottom of the reactor where it enters an efficient water distribution system and is then mixed with anaerobic granular sludge in the reactor. In the lower part of the reactor, namely the main processing zone, most organics are converted to methane and carbon dioxide. Biogas is collected by the lower part of the three-phase separator, producing gas lift power to push water through up-flow column into gas-liquid separator on the top of the reactor. Biogas is separated in the separator while water flows back to the bottom of the reactor. Hence the name Internal Circulation reactor. In the second section of the reactor, namely the upper part, wastewater is further treated. In this part, the produced biogas is collected by the three-phase separator and clean water is discharged from the top of the reactor. An IC reactor is a vertical tank with a height ranging from 16 meters to 28 meters and a diameter ranging from 2.2 meters to 20 meters. -
$2.00Clear EGSB 膨胀颗粒污泥床
Clear EGSB 膨胀颗粒污泥床 EGSB反应器是在UASB概念上发展而来。 与UASB反应器相比，EGSB反应器增加了回流，流速和传质。 因此EGSB反应器具有较高的处理效率和运行稳定性，已被广泛应用于废水处理。 EGSB（Expended Granular Sludge Blanket）膨胀颗粒污泥床是在UASB概念上发展而来，利用颗粒污泥良好的沉降性能，可以在更高的上升水流工艺条件下膨胀污泥床层，同时避免污泥流失，因此，混合污泥浓度更高，容积负荷更高。 危险的是，在高上升水流和截面密集产气的情况下，污泥流失变得严重。 因此，顶部三相分离器放弃了集气功能，从而固液分离得以加强，沼气通过密闭的顶部收集引出。
The EGSB reactor makes full use of anaerobic granular sludge technology. It provides sufficient up-flow velocity for the reactor through the external circulation and ensures the expansion of granular sludge blanket, makes sure that the matters inside the reactor are fully mixed, and as a result improves the efficiency of the reactor. Wastewater of high concentration is pumped into EGSB from the bottom by the water distribution system and is then mixed with anaerobic granular sludge in the reactor. Most organics are converted into methane and the gas-liquid separation module separates methane, water and sludge. The biogas enters transport system from the top while the wastewater flows into the following processing system and anaerobic sludge returns to the sludge blanket. Technical features are as follows: 1.External circulation system 2.Efficient separation module 3.High sludge concentration 4.High volume load 5.Small footprint 6.Low cost -
