Tubular type module

Tubular type module

Tubular modules are suitable for high-concentration solid-liquid separation treatment.
The waste water from buildings, ships, communities, etc. are recycled more often these years. The membrane method is adopted in the processes above for solid-liquid separation and reduction of BOD, COD and SS. Tubular modules have membrane inside the pipe whose inner diameter is at least 10mm, and suitable for turbid solution and water quality with a large amount of suspended solids which cannot be treated with hollow fiber modules. Main purposes of use are gray water, treatment of human wastes, concentration of enzyme, etc., and they are also suitable for desalinization of dye, concentration of tomato juice, etc. using reverse osmosis membrane.

Features of tubular type modules

Optimal for high-concentration solid-liquid separation
They are suitable for treatment of high-viscosity turbid solution and waste water with large amount of suspended solids. It is possible to select the membrane pore size and the membrane material according to the conditions of the treated waste water.

Easy maintenance
It is possible to perform physical cleaning (sponge ball cleaning) as well as cleaning with chemical agents. Since replacement of membrane is also easy, the maintenance does not become a burden.
