A waste treatment settling tank treats an industrial waste inflow (QIN) of 0.2 m3/s with a suspended particulate concentration (

CIN) of 2000 mg/L. The settling reactor has a sludge flow (SS) to a centrifuge of 360 grams/s, and a flow (QS) of 0.050 m3/s. The centrifuge has a return flow (QR) to the settling tank of 0.048 m3/s and a concentration (CR) of 408 mg/L.
1. What is the effluent flow (QE, in m3/s), concentration (CE, in mg/L) and particulate mass flow (SE, in grams/s)
2. What is the concentration (CDW) and particulate mass flow rate (SDW) for the dewatered sludge?

The effluent flow in concentration and particulate mass flow will be 0.198m³/sec.

<h3>How to calculate the effluent flow?</h3>

It should be noted that the total inflow will be equal to the total outflow. Therefore,

0.2 + 0.048 = 0.05 + We

Collect like terms

Qe = 0.2 + 0.048 - 0.05

Qe = 0.198m³/sec

The concentration will be:

= (360 × 1000)/0.05

= 7200mg/L.

Na⁺,SO₄²⁻ is the answer

<h3>Further explanation </h3>

An ion is an atom or molecule that has a net electrical charge. There are many ions, one of them are sodium ion and sulfate ion.

SO₄²⁻ or Sulfate is a naturally occurring polyatomic ion that consist of a central sulfur atom surrounded by four oxygen atoms with occured widely in everyday life. Sodium ions are important for regulation of blood and body fluids, transmission of nerve impulses, heart activity, and certain metabolic functions.

Whereas Na⁺ or Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sulfate ion is a very weak base. Therefore sulfate ion undergoes negligible hydrolysis in aqueous solution.

Enter the symbol of a sodium ion, Na⁺, followed by the formula of a sulfate ion, SO₄²⁻. Separate the ions with a comma only—spaces are not allowed. Express your answers as ions separated by a comma. Therefore the answer is: Na⁺,SO₄²⁻

Hope it helps!

Nady [450]

Answer:

0.825 M

Explanation:

The osmotic pressure is a colligative property, that can be calculated using the following expression.

π = M × R × T

where,

π is the osmotic pressure

M is the molarity

R is the ideal gas constant

T is the absolute temperature (24°C + 273 = 297 K)

M = π / R × T = 20.1 atm / (0.08206 atm.L/mol.K) × 297 K = 0.825 M
