Pumping and filtering water from river

Is there a pump and filter system that will run on DC power and provide water on a camp that is 30ish feet from the river? And at the same time filter the water?
 
From what I understand, its easier to push water then pull it. Either way, its going to be a pretty good power draw. Filter wise, I use Garden Hose Filters at home. Those take about 50% of the flow away. That just made your pump draw more power. How much restriction is based on how well you want to filter it. Also, don't pull any muck into the filter. Clean water only.

Short answer is yes but you need to do some math then research. Distance and elevation gain.
Lift water 30 feet is about 1 hp. Horizontal 30 feet with no elevation gain is about .25 hp. ( I don't know the diameter of the hose these numbers come from. I'm guessing 1")(I also dont know the flow rate. Again guessing at 10gpm)

1hp is about 746 watt. 746w/12v=62 amp (1hp). 62/4=15a (.25hp)
62a to lift 30 feet @12v or 15a to move flat 30feet @12v

Next calculate your filter. My filter has about 50% restriction so double what number you get.
This is off the top of my head without calculating wire loss. Obviously these numbers are based on flow rate. I just looked up what it took HP wise to move the water then calculated power based on 12v. Looking at 12v well pumps, I only saw 1/10 hp. based on the numbers, those I saw are too small.
A bit of research is needed. My calculations will get you started and at least ballparked.
So, yes doable but possibly costly.

For me, its easier to fill a water can then drag it to camp and filter it there. Smaller pump and filter.
