Data transfer to the PC requires the DiverMate/PC Interface Card, supplied with the DiverMate and software. Both the data and the logger settings are downloaded, one file at a time, avoiding any possible identification problems.

Nanofiltration membrane eliminates need for hybrid system
The new ESNA1-LF low fouling nanofiltration membrane provides salt rejection of 90% and controlled hardness removal, eliminating the need for hybrid membrane system designs. These low-pressure membranes significantly reduce operating costs by lowering power consumption, while providing a non-aggressive low TDS permeate water. The low fouling technology also reduces the cost of chemicals and labour associated with more frequent membrane cleaning.
The ESNA-LF membrane element is available in both four- and eight-inch diameters, 40-inch long configurations, and produces lower colour and disinfection by-product formation potential than standard lime softening processes. ESNA1-LF can be used as an independent system or part of an Integrated Membrane Solution™ (IMS) design. The system treats brackish feedwater sources for municipal potable applications.

UK approves Envirocheck HV sampling capsule
The UK Drinking Water Inspectorate approved Pall Corporation's Envirochek™ HV sampling capsule for its continuous Cryptosporidium monitoring programme. The UK requires constant monitoring of drinking water for this parasite using only sampling products that have passed its rigorous qualification process.
Cryptosporidium, one of the leading causes of waterborne disease in humans, can be found in 70 percent of the world's water supply.
Multiple outbreaks of Cryptosporidium, a microscopic parasite found in animal and other organic wastes are reported annually. While everyone is at risk, those with weakened immune systems are especially vulnerable. There is no effective treatment for Cryptosporidium infection.
Continuous monitoring with the Envirochek HV capsule confirms system performance on a real-time basis and provides an added margin of safety regardless of the technology used to process drinking water.

Low-Flow cell provides monitoring alternative
A new Low-Flow Cell for the Multi-Parameter TROLL 9000 water quality probe attaches directly to the sensor side of the MP-TROLL 9000, allowing direct flow-through sampling. The new Low-Flow Cell is an optional accessory.
Low-Flow sampling has become a widely accepted method for monitoring groundwater that provides immediate data and lowers laboratory costs when regulations allow. This method also offers an alternative to in-situ monitoring as well casings decrease in size. Additionally, Flow Cells are preferred for monitoring DO and ORP readings that can be altered if exposed to the atmosphere.
