- Jar testing was performed using alum on a raw drinking-water source that contained an initial turbidity of 20 NTU and an alkalinity of 35 mg/L as CaCO3. The optimum coagulant (alum: Al2(SO4)3•14H20) dosage was determined as 18 mg/L with a final turbidity of 0.25 NTU. Determine the quantity of alkalinity consumed as mg CaCO3 (1 significant figure)Determined and fil-up the unknown data of the given table.

The solids are 70% volatile with a specific gravity of 1.05 and the remaining are non-volatile. Find the volume of volatile solids in m³ after digestion, which reduces volatile solids content by 50% and decreases the moisture content to 90%. Report your answer correct to two decimal places.

- Hello can you help me solve this. Calculate the suspended solids in mg/L given the following data: Weight of crucible: 21.0256 g, Weight of crucible and dry solids: 21.0301 g, Weight of crucible and ash: 21.0263 g, and Volume of sample filtered: 50 mL. Answer should have 2 significant figures.Q1.Clearly indicate if each of the following is True or False 1) The amount of bypassed water in split treatment of hardness depends on material balance on Mg². 2) Most water treatment plants in Iraq are using polymers as a coagulant. 3) In drinking water, most of alkalinity comes from SO4². 4) Circle or ring system is the most common method used now to design water distribution systems. 5) Fecal Coliforms and E-Coli are generally pathogenic and we need to test them to avoid their diseases. 6) In flocculation process, we need rapid mixing to enhance formation of flocs for better settlement. 7) In filtration, the only mechanism involved is the straining. 8) It is better to travel downhill, avoid rush hours, and avoid left turn when designing a route for packers. 9) Ozone in Stratosphere layer helps prevent UV light from reaching earth and causing skin problems. 10) Transfer station is used to transfer solid waste to final destination in more efficient way.i need correct solution asap in 20 mins
