Sediment
The entry of sediment, specifically those less than 2mm in size, into our water systems can have detrimental effects on the quality of water and the surrounding ecosystem. To help you comply with site erosion and sediment control regulations, we provide a range of services including testing of site water for total suspended solids and pH levels, as well as bench testing and flocculant control methods for Chemical Treatment Management Plans (CTMP).
Bench Testing
The bench testing process is carried out using a six-jar overhead stirrer, which imitates the mixing and settling conditions in a clarifier. Different amounts of flocculants are added to the sample to identify the most appropriate option for the sample type. Terra Scientific is proud to collaborate with Cirtex Industries and provide bench-testing services.
Testing is conducted in accordance with ASTM D2035-13 Standard practice for Coagulation-Flocculation Jar test of Water and Auckland Regional Council GD05 and TP227 guidelines.
Sedimate™
Terra Scientific is proud to be working alongside Aqualutions as the main distributor for Sedimate™!
Recognised by Environmental Canterbury, Sedimate™ is an efficient and economical approach to manage site sediment discharges in a timely and practical manner. With Sedimate™, you can rapidly make an informed decision for your site water discharge.
Every Sedimate™ is customised to the specific combination of soil types and desired quality of discharge applicable to your site. This is achieved by using a sample of water with sediment collected from the site for the creation of each Sedimate™. Each Sedimate™ kit consists of three jars contained within a handy and sturdy unit. The jars are calibrated from the site-specific sample to be below, at and above the TSS compliance limit required for the site.
