Wastewater Treatment Equipment

Wastewater can be generally divided into the two categories: inorganic and organic. Nakagawa Chemical Equipment (NCE) develops wastewater treatment equipment utilizing the latest treatment technologies, matched to the specific type of water to be handled.
Although treatment methods vary depending on the type of wastewater and substances contained therein, we provide the optimal wastewater treatment to meet a customer’s needs, with reliable treatment plan of low running cost and power-saving.

Wastewater Treatment Equipment Lineup

Flocculation-Sedimentation Equipment

This equipment removes heavy metals, suspended solids (SS), colloidal substances and other substances found in inorganic wastewater.
Hazardous substances in the water can be quickly separated and precipitated out.

Pressure Flotation Equipment

This equipment treats wastewater through generation of micro-bubbles to remove high-concentration oils, suspended solids (SS), etc.
These tiny bubbles adhere to the substances and separate them via flotation to the top in a short period of time.

Biological Treatment Equipment

Biological treatment is the most common method of treating of organic wastewater.
NCE recommends an aerobic wastewater treatment approach. We offer treatment methods tailored to the contents of the wastewater to be treated.

Nitrogenous Wastewater Treatment Equipment

Nitrogenous and phosphorus substances in industrial wastewater must be removed thoroughly for the protection of natural environment.
NCE can provide nitrogen removal technologies through this equipment, based on the knowledge that NCE has acquired from the experience of wastewater treatment for long time.

Wastewater Recycling Equipment

Water shortages, stricter wastewater discharge regulations, steep cost increases for sewerage discharge—wastewater recycling equipment plays a major role in overcoming these types of problems and protecting the natural environment.
