IW Tremont now offers time saving, Pre-Washed and Pre-Weighed versions of both VSS and TSS specialty filters that remove processing steps to maintain quality and repeatability
Water/Wastewater treatment methods
Water/Wastewater treatment methods utilize glass fiber filters in significant volumes for these test methods:
Determination of Volatile Suspended Solids
"The residue of TSS, TDS after heating to dryness for a defined amount of time and at a defined temperature is defined as Fixed solids. Volatile solids are those solids lost on ignition (heating to 550º C.) They are useful to the treatment plant operator because they give a rough approximation of the amount of organic matter present in the solid fraction of wastewater, activated sludge and industrial wastes".
Recommended Filtration Media Products
- 934-AH® - industry standard for suspended solids content and related measurements
- Grade VSS® - interchangeably equivalent to 934-AH® and ideal for high heat applications
- 934-AH® - Pre-Washed and Pre-Weighed per US EPA Standard Method 2540 C, D & E
Washed, dried, desiccated and fired to 550°C
Weighed to 4 decimal place resolution
Individually packaged in a pan with human readable serial number, weight and barcode
Industry standard 934-AH® glass microfiber filter, ready to use
Meets requirements for use with VSS and TSS analysis

Determination of Total Suspended Solids
"Suspended solids are those that can be retained on a water filter and are capable of settling out of the water column onto the stream bottom when stream velocities are low. They include silt, clay, plankton, organic wastes, and inorganic precipitates such as those from acid mine drainage."
Recommended Water Filter Products:
- Grade TSS – widely used for testing dissolved and suspended solids in water and wastewater
- Grade E - economical media for suspended particle analysis in water, up to 500°
- Grade TSS - Pre-Washed and Pre-Weighed per US EPA Standard Method 2540 C, D & E
Washed, dried, desiccated and weighed to 4 decimal place resolution
Individually packaged in a pan with human readable serial number, weight and barcode
IW Tremont Grade TSS binderless glass microfiber 1.5µm retentionr, ready to use - Grade TSS - Pre-Washed but not pre-weighed
Processed per EPA Standard 2540 C, D & E using reagent grade water (RGW) under strict controls to wash away extraneous fiber
Packaged within plastic container, in stacks with no pans or bar coding
Effective time saver removes a step from work flow, maintains high levels of quality assurance
Toxicity Characteristic Leaching Procedure Method Scope
"The TCLP is designed to determine the mobility of both organic and inorganic analytes present in liquid, solid, and multiphasic wastes."
Recommended Microfiber Filter Media Products:
- Glass Microfiber Grade TCLP – binderless glass microfiber filter media with a particle retention of 0.7µm. Acid treated and multi-stage deionized water rinsed to conform to EPA Method 1311. Saves time and waste disposal expense in the lab by eliminating technician acid treating and rinsing procedure.
