Rapid Fiber Filtration System - “MARIMO”

Water & Soil Water Quality Improvement / Water Management Technology Water Supply / Sewerage

Water & Soil Water Quality Improvement / Water Management Technology Water Treatment Membrane

Technology / Service Summary

“MARIMO” enables pretreatment of water purification facilities (turbidity removal) and advanced sewage treatment, is one of our solutions to meet the needs of water.

Purpose

Application: High-speed fiber filtration system for SS and Turbidity removal
Target: clean water, sewage, recycled water, wastewater, industrial water

Feature

① Smaller installation space
A large amount of water can be processed and because it is a small device, it can fit in a very limited space.

② Low operational cost
The low power cost of the filtration pumps allows users to enjoy significant savings in terms of energy cost. In addition, the fiber filter replenishment is less than 1% per year, keeping the total operating costs very low.

③ High filtration performance
The high turbidity of raw water can be filtered to less than 1 NTU by combining aggregation precipitation equipment with “MARIMO”.

Effect

The fiber filter material used for "MARIMO" is specially processed polyester fiber and has high-speed filtration and high filtration performance that can achieve SS removal equal to or less than sand filtration. We believe this is the area where we can contribute to the SDGs.
