Based on natural, non-polluting substances whose raw materials are coral fossils, mollusc shells, seaweed and minerals, the PW1 reagent is high-performing, safe and very easy to handle. It can treat any type of wastewater and can be used in both fresh and salt water.
Moreover, it contains no substances harmful to the environment.
Non pollutant. Made of mollusc shells,seaweeds and minerals.
Harmless for human beings,animals and plants.
One single compound, powdered
Easy to handle and dose.
Integrates coagulation and flocculation processes.
High-quality resulting sludge
Easy to dewater.
Treats any kind of water
Low sensitiveness to pH, temperature, turbidity, salinity…
Offers its highest efficiency when used in NIHON KASETSU’s machine,but can be used with superb results in any other clarification process available in the market.
Most importantly, they comply with environmental regulations. It is very important to know if either the excess sludge or treated water contain parts of flocculant in their composition, so it is very important to know what type of flocculant is used.

Advantages over conventional reagents
The main advantages of the NIHON KASETSU reagent compared to conventional flocculants are:
- It is inorganic, and composed of 100% natural raw materials, such as algae, mollusc shells, coral and minerals. It is environmentally friendly and safe to handle.
- It has a very short reaction time and achieves a high rate of sedimentation.
- Gives better treatment performance, with greater reductions in SS, COD and BOD.
|Comparsion of Advantages|
|Parameter||NIHONKASETSU reagent||Conventional method (PAC + Polymer)||Comments|
|Treatment equipment||Compact||Very voluminous||Provides 60-80% space saving.|
|pH||Not necessary (if the waste water is neutral)||Necessary to control||PAC is very acid, with a pH of 3-4|
|Sludge recycling||Can be recycled (e.g. if the waste water has no heavy metals)||Cannot be recycled (sludge has to be treated as industrial waste)||–|
|Sludge appearance||Sludge very dry (low viscosity)||Sludge very viscous||Water is more difficult to remove from highly viscous sludge|
|Adding too much flocculant||This is not a problem||The water turns white||–|
|Flocculant dispensation and control||Very easy (single agent)||Difficult (2 agents)||PAC and polymer amount has to be properly controlled in the conventional method.|
|Handling||Safe and easy||Difficult||Some PACs and polymers contain harmful substances.|
|Environmental friendliness||Very high||Low||The NIHON KASETSU reagent is composed of natural minerals.|
|Environmental impact||0.65||Significant||Some PACs and polymers contain harmful substances.|
