Biogas Cleanup Methods

Cleanup of biogas is primarily achieved by carbon dioxide removal which enhances the energy value of the gas to give longer, driving distances with a fixed gas storage volume. Removal of carbon dioxide also provides a consistent gas quality with respect to energy value. The latter is regarded to be of great importance from the vehicle […]

Understanding Reverse Osmosis Filtration

RO-water-filtration

The reverse osmosis filtration is a method that filters water through a semipermeable membrane with small pores. It allows the water molecules to pass through, and contaminants are left outside. The purified water called permeate is collected while the water with contaminants called waste is flushed away. For instance, chlorine is filtered off when chlorinated […]
