Lignite is treated to provide an activated carbon with a high mesoporosity and total surface area. The starting material has a high ash content, such as greater than 10% by weight.

A filter apparatus for treating hydrocarbon contaminated water comprising a housing defining an internal cavity and having an inlet and an outlet; a separating member that separates the internal cavity into a first treatment zone and a second treatment zone, wherein the first treatment zone is in fluid communication with the inlet and the second treatment zone is in fluid communication with the outlet, the separating member having one or more holes therethrough for fluid flow from the first treatment zone to the second treatment zone; at least one distribution tube within the second treatment zone having an end enclosing at least one of the holes to accept liquid flowing through the hole, the distribution tube further having perforations along its length for distributing liquid into the second treatment zone; a filtration barrier within the first treatment zone for removing particulate matter from the liquid flowing therethrough; and a particulate filtration media within the second treatment zone, surrounding the distribution tube, comprising at least one polymer for removing hydrocarbons from the water flowing through the second treatment zone prior to exiting the outlet.

A biodegradable filter for the removal of various pollutants, contaminants, or harmful substances from the surrounding air, and a method of fabrication. The filter includes 30% by weight of cellulose nanofibers, 30% by weight of activated carbon, and 20% by weight of polyethylene glycol. The cellulose nanofibers and activated carbon are isolated from date palm biomass, making the filter cost-effective and environmentally friendly.

Disclosed is an energy hydrogen water dissolving device that passes a clean water source through a pressurized pump. A part of the water is sent to a hydrogen production equipment and decomposed into hydrogen and oxygen, and the other part of the water is driven to an energy hydrogen water dissolving and storage tank. The oxygen formed by the hydrogen production equipment is discharged to the outside or returned to the clean water source, and the hydrogen formed by the hydrogen production equipment is connected and sent to an input end of the pressurized pump, pressurized and mixed uniformly by the pressurized pump and outputted to the clean water, so that the water liquid entering into the energy hydrogen water dissolving and storage tank becomes high dissolution hydrogen water. The energy hydrogen water dissolving and storage tank contains an energy mineral, a hydrogen molecule mineral and a terminal filter, and the water liquid discharged from the energy hydrogen water dissolving and storage tank is formed into healthy drinking water with tiny water molecules, weak alkaline, high negative potential and high dissolution hydrogen molecules
