Pure Water System
A wide range treament of wastewater for industry, construction and mining sectors
Wastewater contains suspended particles in a wide variety of shapes, sizes, densities and composition. Many chemical and microbiological contaminants found in wastewater are absorbed or incorporated into the solid particles. Therefore the efficient removal of suspended solids is essential for the treatment and recycling of waste and industrial water.
At NIHON KASETSU, in addition to our innovative, naturally occurring, inorganic flocculant, we have developed compact and light water treatment equipment that offers high efficiency and performance, while being extremely environmentally friendly. It can be installed almost anywhere and is very easy to assemble and operate.

The Process of Coagulation and Flocculation
An essential stage in the decontamination of water is clarification, which is the physical and chemical process to remove particles that make the water cloudy, i.e. suspended solids, which precipitate in the form of sludge.
The suspended particles are negatively charged which means they are constantly moving.
Coagulation is the process of destabilisation and subsequent aggregation of particles in colloidal suspension in water. Flocculation is the agglomeration of these destabilised particles in larger flocs which can be decanted and filtered.
For both processes to occur, it is necessary to add substances called coagulants or flocculants.
The flocculation process is preceded by coagulation, so the whole process is often called coagulation flocculation.
NIHON KASETSU PW1 reagent contain positively charged substances that attract particles in colloidal suspension. The agglomerations then combine with other mineral compounds and settle as sludge.

Reagents
PW1, the most efficient and ecofriendly solution
There are many different types of coagulants and flocculants used for water treatment. The conventional aluminium-based polymers have some significant drawbacks: e.g. they are environmental pollutants, a large amount of product is required, they are toxic, difficult to handle and can cause diseases such as cancer and Alzheimer’s disease.
