BLUWAT F7 is a highly active cationic inorganic coagulant with efficient clarifying effect in municipal and industrial wastewater treatment, significantly improving biochemical efficiency and improving the removal rate of pollutants in biochemical processes by improving the characteristics of activated sludge. BLUWAT F7 is a coagulant for nanotechnology and has many advantages in biochemical processes.

BLUWAT F7 can obtain a better floc structure, which greatly improves the sedimentation performance of activated sludge, improves the density and activity of MLSS and beneficial bacteria in the biochemical process, and greatly improves the treatment efficiency. This product is used for the treatment of municipal sewage and industrial wastewater.

The BLUWAT F7 is manufactured in European factories, imported and sold domestically and serviced by Bluewave.

Better flocculation and sedimentation

Increase the removal rate of biochemical COD, BOD, TSS, TN and TP by 30%~60%

Prevents sludge floating and expansion problems

Promote the growth and reproduction of bacteria in the aeration tank

The amount of sludge is reduced by 30%~40%.

Improve the dewatering performance of sludge

Reduce wastewater treatment costs

Technical parameters:

index	numeric value
appearance	Green to brown
Fe+2, %	7.5-8.5
Chloride, %	0.42-2.5
Density g/cm3 20 °C	1.2±0.1
pH	1-3

BLUWAT F7 should be dosed directly and should not be diluted. Diaphragm metering pumps with corrosion-resistant materials are suitable.

Dosing point: after the aeration tank and before the second sedimentation tank

1. The first impact dosing, the maximum dosage is 15 ppm, until the sludge in the aeration tank is completely cycled for 2 times, and it is added for 3 days.

For example, a wastewater plant treats 100,000 m3/day x 15 ppm = 1.5 t of BLUWAT F7/day.

Maintain this dose until the sludge is completely circulated in the aeration tank, which will be dosed for 3 days.

2. After 3 days, reduce the dosage to 10 ppm, so the dosage is 1 ton of BLUWAT F7/day, and add 2 days.

After 5 days, the entire biochemical system will have a significantly improved flocculation effect because BLUWAT F7 is already working.

3. Maintain the normal dosage of 5 to 3 ppm after 5 days, and the dosage is 300-500 kg of BLUWAT F7/day.

COD, BOD, TN and TP will decrease from day one and will be better after a few days. Then, continue with low dosing as normal operation.

It is important to inform wastewater treatment plant staff that there are no changes in their daily operations of the wastewater plant. Simply ration the products of the BLUWAT F7 and they check the effluent parameters daily according to the daily working protocol.

If you stop dosing BLUWAT F7, the next time you use it, you need to restart the above process and start from 15ppm to get better performance.

Packing: ton drum, 1250 kg; 250KG plastic drum, 24 tons flexitank

The recommended validity period of BLUWAT F7 is 10 months, and the packaging must be stored airtightly. Storage tanks and pipes should be made of suitable non-corrosive materials, such as FRP or cross-linked polyethylene plastic.

Laboratory Test Procedures:

Take 2 1 liter graduated cylinders

Fill the wastewater and sludge from the aeration tank to 1000 ml

Mix them gently

Add 1 drop of BLUWAT F7 product to one of the graduated cylinders

Gently stir with a glass rod for 4 to 5 sec to allow all the liquid in the graduated cylinder to mix

Remove the glass rod

Observe the time of sludge settlement. (It will be very fast in the first minute, then it will slow down; Record sludge sedimentation values in minutes/ml)

Wait 30 min and record the final readings of the sludge in both graduated cylinders

Get the results of the BLUWAT F7 product

Samples were taken from the top clean water of the two graduated cylinders to measure COD, BOD, TSS and TP

Applicable items:

The settled of activated sludge is relatively poor, so the sludge settlement ratio is improved and the effluent index is improved

There are sludge expansion and sludge floating problems

The sewage plant is upgraded to improve the removal rate of COD, BOD, TSS, TN and TP

Reduce the load of tertiary treatment in sewage plants or replace tertiary treatment altogether

Partially replace and fully replace the addition of ordinary polyaluminum chloride, polyiron and other flocculants to reduce the amount of chemical sludge

Increase the influent load of the sewage plant and increase the sewage treatment capacity of the existing facility

Improve the stability and reliability of sewage plant operation

Zibo Limin Purified Water Co., Ltd. is entrusted by the Zichuan District Government to build and operate the Zichuan District Urban Sewage Treatment Plant, which undertakes the treatment of urban sewage and industrial wastewater in Zichuan District, Economic Development Zone and nearby townships. Zibo Limin Purification Water Co., Ltd. has a design treatment capacity of 80000,31962 tons/day, designed influent water quality "Sewage Discharged into Urban Sewerage Water Quality Standard" (GB/T2015-18918), and designed drainage water quality "Urban Sewage Treatment Plant Pollutant Discharge Standard" (GB2002-20000) Class A requirements. The sewage treatment process adopts the treatment process of "anaerobic hydrolysis + Obel oxidation ditch + high-density sedimentation tank", and the company also has a "ultrafiltration + reverse osmosis" reclaimed water reuse project of 2017,<> tons / day, which is a relatively good operation and management enterprise in Zibo municipal sewage treatment plant. In <>, the Zibo Municipal Government put forward the requirements for the upgrading of the city's sewage treatment plant, and Limin Purified Water successfully completed the transformation work through internal transformation according to its own conditions. However, there are problems of high operating costs and low biochemical processing efficiency in operation.

In response to these problems, our company provides a nano-accelerator. This product is a flocculant mixture based on large molecular weight Al2O3 and Fe and nano-iron, which has a higher positive charge density than other flocculants, so it has a more efficient use effect. Its efficient flocculation effect effectively solves the problems of sludge expansion and high SVI; The stronger combination of sludge flocs can provide a better carrier for microbial aggregation and continuously reduce the indicators of COD, BOD, suspended solids, TP and other indicators in the effluent; Due to the formation of large and stable flocs, the system achieves a faster nitrification/denitrification process, improving the removal effect of TN, so that a large amount of air is no longer required, which extends the service life of the compressor; Due to the formation of large and stable flocs, the sludge concentration effect is also improved, the chemicals used for subsequent sludge treatment are reduced, and lower moisture content can be obtained, reducing the cost of sludge treatment.
