The results of a laboratory study to investigate the feasibility of utilizing Hydroperm filtration to treat the waste from the MUST hospital complex are presented. Hydroperm filtration utilizes rugged, thick-walled thermoplastic tubes of controlled microporosity to achieve almost total removal of suspended solids and significant removal of dissolved solids from waste streams even at relatively low filtration pressures typically 5 psi or 0.35 kgsq cm. A unique feature of the tubes is that their pore structure can be matched to the size and nature of the suspended solids in different waste streams so as to obtain optimum filtration performance under a variety of test conditions. This optimization procedure is illustrated in the present study for MUST wastes by performing controlled laboratory tests with tubes of different pore structures. It is shown that Hydroperm filtration yields very good results even at extreme conditions of feed pH down to 2.0 and temperature down to 4.4 C, without experiencing fouling or clogging such extreme feed-waste conditions are likely to be encountered during the operation of the MUST hospital complex.
