DEWA A-P automatic polymer preparation systems is an important part of effective and reliable wastewater treatment process. It is applicable for both municipal and industrial applications. The batch preparation technology guarantees the best possible concentration formation. All of the DEWA polymer preparation A-P units are designed for one
Introduction. Clean water is essential for the survival of life on the earth. According to international standards, less than 1% of total water is clean, while, the rest of the water quantity is contaminated by different pollutants , .Major sources of water pollution include industrial wastes, municipal wastewater, and agricultural activities.

Polymer concentration is set via calibration of the dry polymer feed rate and dilution water flow rate. The concentration can be adjusted by programming the desired value into the PLC panel. Standard volumes available from 1 m3 up to 10 m3 with preparation solution strength of 0,05 – 0,4% and can be diluted to required final strength.
For effective coagulation and flocculation in water-treatment applications requiring solid separation, SEKO’s polymer preparation units provide cost-effective automatic or manual batching of liquid and powdered polymers. From single to triple-chamber polymer preparation systems, our all-in-one solutions include compact, space-saving designs that facilitate the treatment of swimming pool
Polymer Applications in Biological Treatment Systems
• Polymer chains vary in length from thousands to millions of monomer units. • If each monomer molecule was the size of a pearl, the chain length of most polymers would be 400 to 8,000 feet long! • In wastewater treatment processes, polymers are used to coagulate suspended solids and produce large curds of solid materials (floc). Monomer Unit
Why? Because everyone has right for clean water. We operate in the water and environmental sectors providing the best quality of planning, engineering, and contracting services including electro-mechanical machinery deliveries. We have a focus on countries, which have growing need for basic infrastructure of water and wastewater treatment.

It must first be dissolved in water before use, using its aqueous solution to wastewater treatment. 2 water should be clean, dissolving granular polymer (such as water), and cannot be a sewage. Water at room temperature, typically do not require heating. Water temperatures below 5 ° c are dissolved very slowly.
A sustainable bio-carrier medium for wastewater treatment
Inorganic carrier media for wastewater treatment can contribute to green and sustainable living. BF was inorganic micro-scale fiber material, mainly composed by inorganic oxides (SiO 2, Al 2 O 3, CaO, Fe x O y and MgO, etc.). It has many advantages like low-cost, green production process and non-toxicity, etc., but has poor bio-affinity.
polymer as follows. (This method will yield less efficient inversion and unwinding of the polymer). a. Use a container with a lid. Measure the water out and add it to the container. b. Rapidly shoot the emulsion into the water using a syringe. With this method, target a 0.1% solution. c. Immediately cap the container and vigorously shake for 1
Ekoton - About Site
“Ekoton” Company was founded in 1995 by wastewater treatment engineers. The Company started its production activity from simple polymer products and with just 8 employees. In
The perovskite-type LaCoO3 was successfully prepared by La(NO3)3 and Co(NO3)2 in citrate acid solution,where the citrate acid was used as chelating agent and fuel.Photocatalytic activities of perovskite LaCoO3 to TNT degradation were studied.For LaCoO3
- What is polyaluminum chloride?
- Introduction Polyaluminum chloride (PACl) is a coagulation agent that has recently begun to be used in water-treatment processes. It is more effective than the existing aluminum sulfate system, and its use is expanding [ 1, 2, 3 ].
- Can polyaluminum chloride be used in water treatment?
- In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.
- What is a preformed polyaluminum salt?
- Polyaluminum chloride (PAC) is a preformed polyaluminum salt that can be produced by adding base to aluminum chloride until an empirical formula of Al (OH)nCl3-n (with n from 1.0 to 2.5) is achieved. A variety of species can be formed when stock solutions of PAC are added to a raw water.
- What is the molecular formula of poly-aluminum chloride?
- One of the major pre-polymerized coagulants, poly-aluminum chloride (PACl) is used broadly for water and wastewater treatment. PACl contains different amounts of hydroxyl, and the molecular formula of PACl is [Al m (OH) n (H 2 O) x]·Cl 3m−n (n ≤ 3 m).
