• Treatment of drinking water for removal of iron, manganese, arsenic, and selenium
• Treatment of drinking water for removal of bacteria such as giardia and cryptosporidium
• Removal of bacteria used in the removal of nitrates and perchlorates from drinking water
• Recycling of cleaning chemicals used in sterilizing beer making equipment
• Removing beer from yeast to reclaim yeast for use as animal feed
• Recycling of water in winery use
• Treatment of wastewater used in chemical mechanical planarization (CMP) of semiconductors
• Mechanical filtering of chrome and nickel process baths

Pictured Above is a 30-40 gallon per minute micro filtration skid. Each stainless steel module contains 24 ceramic elements.

This single ceramic element illustrates cross flow membrane removal of contaminants and production of filtered permeat.

A: Wastewater flows lengthwise through the round bores of the ceramic element.

B: Filtered water exits the stainless steel module or discharge.

BASX Systems uses ceramic filter membranes produced by CoorsTekTM, a leading supplier of advanced ceramic products in the United States. These membranes are made of the highest purity alpha-alumina and other ceramic materials. We have multiple materials and porosities available to meet the needs of any application. Our staff scientists and engineers combine this superior technology with their expertise in chemistry, biology and filtration mechanics to design complete solutions to specific filtration problems. Some of the more significant advantages and benefits of BASX filtration systems are outlined below:

Systems have
low life-cycle cost:

• Expected membrane life is typically > 10 years
• Membrane replacement cost is << polymer membranes
• Cleaning cycles are short and infrequent
• Pumping energy is minimal (20-30 psi.)
• Very low energy required compared to electrowinning or evaporation
• Minimum pumps, controls, valves, and instrumentation
• Compact size ensures ease of maintenance

Membrane is universal:

• Not designed for specific chemistry
• Operates over a pH range of 0 to 14
• Accommodates changes in your process
• Requires only minor adjustments to chemical additives
• Effective for filtering bacteria, organic solids, silts, and other particles as well

Modular filter assemblies:

• System can be designed for growth
• Difficult with clarifiers
• Can be designed for multiple flow types in same plant
• Difficult with clarifiers

Computer Control options:

• Less operator time consumed
• Remote monitoring and control at any time
• Auto-dials for help when needed
• Call up from home to help operator diagnose problems helps prevent discharge violations

Compact:

• Consumes much less expensive floor space
• Filter module/pump skid is small
• Tankage is smaller than clarifier system of same capacity
• Sludge is typically 5% by weight, 40-80% by volume
• Can go straight to sludge press/vacuum drying system

Minimum failure modes:

• "Pin floc" failures not possible
• No secondary filter required
• Ceramic membrane does not degrade with cleaning or chemical exposure
• Impervious to abrasion in typical applications
• Does not develop "channeling"
• Membranes do not become brittle and crack or rupture like polymer membranes

BASX systems qualify as a "Waste
Minimization Program" under RCRA

• Minimizes total waste produced
• Allows flows to be segregated into hazardous and non-hazardous waste
• Separating RCRA subtitle d solid waste (including Zn) minimizes disposal costs
• RCRA subtitle c hazardous waste is not mixed so is very much smaller quantity

Minimizes chemical use

• High % solids so no thickeners required
• No flocculation polymers required
• Runs closer to ideal precipitation pH so less additives required

Less solid waste generated

• Less chemicals used
• RCRA advantage, can afford to split hazardous /non-hazardous wastes

Effluent quality is high

• more water can be used directly
• 0.06 NTU (Nephelometric Turbidity Units)
• < 2 ppm TSS (Total Suspended Solids)
• Makes ideal feed for RO
• < 1 SDI (Silt Density Index)
• Water re-use is high for most industrial applications

Ideal for many potable-water applications

• > 6 log reduction in total coliform
• Absolute filter prevents passage of Cryptosporidium and Giardia
