gas bottle, rubber hose. The quantity of local materials and control set up (i.e. Iron oxide and quicklime) were 250g each. METHOD . The method involves removal of nonbiodegradable materials from the biodegradable biomass. The biomass was - reduced to smaller sizes by cutting it with knife. The biomass was mixed with water in a ratio of 1:2.

Fine purification method for rubber vulcanization
The method comprises the following steps: crude thiofide M is extracted by using toluene for three times to remove resin impurities so as to obtain high-purity thiofide M the thiofide M in the resin is purified by the alkali dissolving and acid isolation method and the thiofideoluene is reclaimed by a distillation method.

Basic Equipment and Materials for Bottle/Sachet Water
Basic Equipment and Materials for Bottle/Sachet Water Production in Nigeria. The submersible pump is meant for factories that use boreholes instead of municipal or other water source. All the pumps must not be made from galvanized metal. Three (3) Storage Tanks are ideal. One tank for Raw Water storage, another for treatment process and the third tank for post-Treatment water Storage.
