Applying the extension method on low temperature wastewater reuse;

This research aims to improve the treatment of low-temperature sewage by immobilizing psychrotrophs to the treatment system.

This article describes the heat pump-type crude oil heating system and associated technologies and validates the feasibility,through theoretical calculation,of using the heat pump-type crude oil heating system to recover residual heat from high-temperature sewage in oilfields.

The objective to measure the sewage turbidity when dilution diffusion model of sewage is tested for discharging sewage into the sea is to research and calculate the dilution rate of the sewage in the water.
